T0 all whom t may con/cern:

Be it known that I, EUGNE MOREAU, a citizen of the Republic of France, residing at New York, in the county of New York and State of New York, have invente-d a certain new and useful Valve, of which the following is a specification.

The object of the present invent-ion is to provide a reliable valve which shall automatically open when in one position and which shall automatically close when turned in to any other position or positions and which shall again automatically open when returned to the position first hereinabove referred to.

Another object of the invention is to pro-1 vide a valve especially adapted for the gasway of portable acetylene-generators or table-lamps by reason of its remaining open only when the generator or table-lamp is in upright position and of its being automatically closed in the event of the overturning of the generator or table-lamp, whereby passage of water through the gasway is prevented and absolute safety insured.

To these and other ends hereinafter set forth the invention, stated in general terms, comprises a valve and its seat and a pendant afforded movement in all directions and adapted to control the positions of the parts of the valve in respect to each other.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in whichW Figure 1 is a view illustrating, principally in central section. a valve embodying features of the invention and showing the parts in position for opening the way through the valve. Fig. 2 is a similar view illustrating the position of the parts of the valve whereby the valveway is automatically closed, and Fig. 3 is a similar/view illustrating the valve of my invention in application to an acetylene portable table-lamp.

In the drawings, 1 is the valveway. 2 is the valve, and3 is a pendant. The pendant tends to hang vertically, and when the parts 1 and 2 or the structure which carries them is shifted out of predetermined position the pendant by reason of its weight operates to shift the part 2 in respect to part 1 in such a way that the valveway is closed. As illustrated, the valve 2 is of the plunger type and is provided with a suitable face 4, as of rubber,.

in any direction-for example, into the posil tion shown in Fig. Q-the pendant 3 tries to assume under the influence of gravity an upright position. In doing so one portion of the head 10 turns about the rim 9 as a fulcrum, and the diametrically opposite portion of the head 10 pushes upon the valve 2, and thus shifts it and holds it against the seat 1. Since the head 10 and rim 9 are circular, it follows that the described operation will occur no matter in which way the casing may be tipped from its normal position.

In Fig. 3, 11 is a water-chamber, and 12 is Aa carbid-chamber. 13 indicates mechanism forming no part of this invention and which is so constructed that it normally prevents the passage of carbid to the water and water to the carbid, so that it would, in case the lamp were overturned, not permit of the passage of water. 14 is the pipe by which gas is normally led from the water or generating chamber to the carbid-chamber, and by providing this pipe with the described valve it is clear that should the lamp be overturned or, in fact, turned out of its upright position the valve operating in the manner described will close this passageautomatically, and thus prevent water from reaching the carbid and in that way obviate all possibility of danger.

It will be obvious to those skilled in the art to which the invention relates that modilications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove-set forth T and illustrated in the accompanyingdrawings; but,

Having thus described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is*

The combination of a casing having a valveway, a spider carried by the casing and provided with a cylindrical passage a plungervalve seated in said passage, and a normally vertical pendant having a shank provided with a circular head, said spider having ports or holds it against its seat, substantially as de- IO Ways and an opening through which the shank scribed. of the vertical pendant Works, said opening Intestimonywhereoflhave hereunto signed having a flange or rinn, the arrangement bemy name. 5 ing such that When the casing is turned out of its proper position a portion of the circular head turns about the rirn as a fulcrunn In presence of- While the diametrioally opposite portion ofthe F. Gr. B. GREEN, head pushes upon the Valve and shifts and M. TURNER.
